FIELD OF THE INVENTION

The present invention relates to safety lighters, and in particular to a safety lighter, wherein a safety structure is used so that the user only needs to press the far end control device at the bottom end by one finger. The thumb serves to ignite the igniter. Thereby a baby or children cannot push the far end control device to ignite. Thereby the danger of firing lighter by children can be avoided.

BACKGROUND OF THE INVENTION

Lighter is widely used. Almost every home has one or two lighters. In general, the lighters are placed anywhere. They are easily taken by children. If the lighter is operated by mistake, a fire accident will occur so as to make the lose of asset or people will be hurt. Since the structure is complicated, cost is high and thus, the price is expensive, moreover, it is not ergonomic, the users will feel inconvenient in use. Thereby the conventional lighter is necessary to be improved.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a safety lighter, wherein a safety structure is used so that the user only needs to press the far end control device at the bottom end by one finger. The thumb serves to ignite the igniter. Thereby a baby or children cannot push the far end control device to ignite. Thereby the danger of firing lighter by children can be avoided.

To achieve above object, the present invention provides a safety lighter which comprises a main body having a sealed pressurized storage chamber for storing fuel for supplying the fuel; a fuel spraying head protrudes from the pressurized storage chamber for opening and closing the pressurized storage chamber; wherein in a first position of the fuel spraying head, the pressurized storage chamber is opened for spraying fuel; when in a second position of the fuel spraying head, the pressurized storage chamber is closed; a fuel supply device installed in the main body; the fuel supply device being capable of inserting into the pressurized storage chamber; a manual igniter installed aside a spraying head of the fuel supply device; and a far end control device installed at or near a bottom of the main body; for controlling the position of the fuel spraying head so as to open or close the fuel supply device. As the igniter is not used, the fuel spraying head is placed in the second position and the fuel supply device is closed; in ignition, the igniter serves to apply a force to the far end control device to control the fuel spraying head to opening the fuel supply device.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIG. 1 to 5, the safety lighter of the present invention is illustrated. The safety lighter includes the following elements.

A main body 1 of the lighter has a sealed pressurized storage chamber 11 for storing fuel 10 for supplying to the lighter.

A fuel spraying head 21 protrudes from the pressurized storage chamber 11 for opening and closing the pressurized storage chamber 11. In position A of the fuel spraying head 21, the pressurized storage chamber 11 is opened for spraying fuel 10, see FIG. 2. When in position B of the fuel spraying head 21, the pressurized storage chamber 11 is closed, as shown in FIG. 1,

A fuel supply device 2 is installed in the main body 1. The fuel supply device 2 is capable of inserting into the pressurized storage chamber 11.

A manual igniter 3 is installed aside a spraying head 21 of the fuel supply device 2.

A far end control device 4 is installed at or near a bottom of the main body 1. The far end control device 4 serves to control the position of the fuel spraying head 21 so as to open or close the fuel supply device 2.

As shown in FIG. 1, as the main body is not used, the fuel spraying head 21 is placed at B position. The fuel supply device 2 is closed. In ignition, as shown in FIGS. 2 and 5, a force is applied to the igniter 3 and the far end control device 4 is used to control the fuel spraying head 21 to open the fuel supply device 2 so as to achieve the object of ignition.

Besides, in the present invention, it is preferable that the fuel 10 is liquid gas.

As shown in FIG. 1, the igniter 3 further comprises an ignition wheel 31 and a flint 32.

In the present invention, the igniter 3 further comprises an electronic ignition device.

With reference to FIGS. 1 to 4, the far end control device 4 of the present invention further comprises a press unit 41 and a driven unit 42.

As shown in FIG. 1, the present invention further comprises at least one channel 12. The channel 12 is formed between an upper portion and a bottom of the main body 1 as a channel by which the far end control device 4 can control the fuel supply device 2.

With reference to FIG. 3, besides, in one preferred embodiment of the present invention, the far end control device 4 is placed at an outer side of the main body 1 for controlling the opening and closing of the fuel supply device 2.

Furthermore, the main body 1 further comprises a mask 13 for protection the far end control device 4.

With reference to FIGS. 1, 3 and 4, the present invention further comprises an elastic element 5 which is installed between the far end control device 4 and the main body 1 for ejecting the far end control device 4 to return to the original position by the pressure releasing of the elastic element 5 when the far end control device 4 is released.

The elastic element 5 may be installed between the bottom of the main body 1 and the far end control device 4, as shown in FIGS. 1 and 2, or installed between the main body 1 and the fuel supply device 2, as shown in FIG. 4.

Referring to FIG. 6, in the present invention, the main body 1 is installed with at least one storing chamber 14 and an end cover 15 for covering the storing chamber 14. The storing chamber 14 severs for storing small objects, such as toothpicks, earflaps, etc.

As illustrated above, in the present invention, a safety structure is used so that the user only needs to press the far end control device 4 at the bottom end by one finger. The thumb serves to ignite the igniter 3, as shown in FIG. 5. Thereby a baby or children cannot push the far end control device 4 to ignite. Thereby the danger of firing lighter by children can be avoided.
